CAN-SOLDERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 400,295, dated March 26, 1889.

Application filea December 27, 1888. Serial No. 294,775. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM D. BROOKS, of Baltimore, in the State of Maryland, IIZING invented a new and useful Improvement in Can-Soldering Machines; and I do hereby declare that the following is a full, clear, and exact description of the same.

Heretofore in Letters Patent granted to me for can-soldering machines and in a pending application of even (late herewith, No. 294,7 7 4, I have represented can-seats with surrounding flame-chambers, with the top plate of the flame-chamber slightly above the can-seat, with burners so located as to direct the flame to the edge of the can beneath the top plate of the flame-chamber, and with solder-feeding devices arranged above the top plate or in line therewith, the flame-tubes and soldertubes being in different horizontal planes. In the present invention I vary the relative arrangement of the flame-tubes and soldertubes, as shown in my patents heretofore granted and in the application referred to, and provide an arrangement by means of which I am permitted to locate the solderfeeding devices and the flame-tube on the same level relatively to each other.

My improved arrangement may be used in connection with the flame-chamber and burner heretofore patented to me in Letters Patent No. 228,864, and I prefer to use the present invention in connection with the same flamechamber; but a simple shield may be provided to take the place of said flame chamber, such as an annular ring.

I have shown the invention as applied to a rotatingtable supporting the can-carriers,with means for continuously rotating the can-seats. The table may have intermittent movement, or may move continuously, and instead of the table shown an endless carrier may be provided, as this is a well-known equivalent of a rotating table.

As my invention applies principally to the means for supporting the can and applyingthe heat and solder thereto, I have not deemed it necessary to show but fragments of the machine.

In the accompanying drawings, Figure 1 represents a side elevation of a can, partly in section, supported upon a can-seat with the .flamechamber encircling the seat, the said chamber and seat being in section. Fig. 2 is a perspective View of a flame-chamber with a can supported therein, showing a solderfeed tube and a flame-tube. Fig. 3 is a plan view of a portion of a table, representing a series of can-seats with the solder-feeding devices and the flame-tube. Fig. 4 is a side elevation, partly in section, of a flame-chamber, a can, and means for raising and lowering a portion of a flame-chamber. Fig. 5 is a sectional view representing the position of the flame-chamber when lowered. Fig. 6 is a view in section of a modification.

In Fig. 1, A represents a flame-chamber of ordinary construction-such as shown in my patent referred to-and in an opening formed in the top plate thereof extends the upper end of the can-seat B. Heretofore I have arranged the can-seat slightly below the upper plate of the flame-chamber, so as to secure support from the walls of the top plate for the sides of the can in its rotation and to prevent it being displaced. In this case, however, as I have before stated, it was necessary to apply the heat below the top plate and to apply the solder above or on a line with said plate. In the present case, in order to form a support for the can, I extend the flanges of the canseat quite up to the edge of the flange of the can, which will give the can sufficient support and prevent displacement until the upper clamp is brought down into place. I am therefore enabled to change the relative position of the top plate of the flame-chamber and the can-seat by arranging the can-seat on a level with said plate, or in such a position as to bring the flange to be soldered with its upper edge above the level of the said plate and in a position to be acted upon by both heat and solder from tubes arranged in the same plane. I secure to the top plate, 0, a shield or segment, d, which extends about a third of the circumference of the top plate, and serves to give support to the cans, and also to prevent scorching or injury to the side seam under the action of the heat from the burner c.

In addition to the burner a, which directs heat into the flame-chamber and against the bottom of the can, I provide the burner e, which is arranged above the plate 0, and in such relation to the can as to direct its flame at a tangent thereto when the said can is being revolved before a solder-station, and it is to protect the can from this flame that I provide the shield d. The flame issuing from the tube thoroughly heats the can on the line of the upper end. of the flange, and the solder-feeding devices, which are supported from the table in direct line with the flametube, and also with the edge of the flange to be soldered, feed. the solder directly to the proper point.

The solder-feeding devices may be of any desired construction; but I pref 3r to use those shown in the pending application referred to of even date herewith, with the exception that a movable support is not necessary in this case, as the seam to be soldered is in a direct line with the soldentube, which in this case is not carried by the upper plate of the flame-chamber, but is independent thereof.

It will be understood that I do not limit myself to the use of the lower burner, u, as this may be dispensed with, though I prefer it, for the reason that a greater heat is thus provided.

It will be understood that with the construction of flame-chamber shown in Fig. l I may use the flame -tubes (0 not only at the heating-stations, but also at the solderingstations, this tube being on one level in line with the opening to the flame chamber, as shown in Fig. 1, with the solder-tube and supplemental flame-tube c on anotherlevel in line with the edge of the can to be soldered, the position of the solder-tube and supplemental flame-tube being represented at c in Fig. 1, this figure showing a can at a solder-station at which both flam e-tubes a and e are utilized.

In Figs. 4 and 5 I have shown a flame-chainher in connection with the can -seats, with means for lowering the upper portion of the flame-chamber during a portion of the r0tation of the table carrying the can-holders, so as to expose the edge of the can, as in Fig. 5, to the direct action of the solder feeding device and to the flame-tube at the solderstation. I provide for this by makin g the upper plate of the flame-chamber movable and connecting it by means of ribs to a sleeve, f, splined to the bracket 9 of the can-holder, so that itmay have up-and-down movement, but no rotary movement, and in order to give it this up-and-down movementI provide a lever, 71, pivoted on a bracket, 1:, and having aloose connection with the sleeve f, as at 7r, with its opposite end provided with an anti-friction roller passing beneath a cam, h.

It will be understood that the upper plate, (2, of the flame-chamber tends constantly to fall by gravity, and the cam h is so arranged that it prevents the plate from lowering until a solder-station is reached, and at this point, through a rise in the cam 71, it allows the sleeve carrying the upper plate of the flamechamber to fall, and this will leave the edge of the can exposed, as in Fig. 5, to the direct action of the solder-tube and the heating-tube at the solder-station, which plays at a tangent on the seam of the can between the plate 0 in its lowered position and the shield (I, which, being attached to the plate 0, lowers with it into proper position. It will be understood, further, that at the heating-statitms proper the flame-tubes a are in a plane to direct the flame into the flame chamber, while at the solder-stations, in addition to the lower flametubc, which may or may not be used, as de' sired, a heating-tube is arranged in line with the solder-tube for the purpose of applying heat to the can during the operation of soldering.

In Fig. I I have shown the carrier in front of the heating-tube a, and in dotted lines at c in the same figure I have represented the position of the upper tla-n'ie'tube at the next solder'station, at which station the top plate, c, lowers and presents the exposed edge of the can to the action both of the heating and solder tubes. After the can has passed the solder station or stations, the cooling-tubes may have full effect against the exposed edge of the can which has just been soldered.

In Fig. U I have shown the top plate, 0, adapted. to be movable in the same way as in Fig. 5, the only difference being that l have shown the top plate alone without the lower part forming the IlftlllO-Cllttll'llJCl.

I claim as my invention- 1. In combiilatioi'i, in a can-soldering machine, a can -seat, solder-feet'ling devices, a flamechainber, a flametnbe, a, for directing heat to the flame-chaml'ier, a second flametube arranged above thelcvel of the first for applying heat to the periphery of the can, a segmental shield supported from the upper plate of the tiame-chamber, and a solder-tube arranged on approximately the same level as the second flame-tube, substantially as de scribed.

2. In (:OlIllJillLllOl'l, in a can-soldering machine, a can-seat, a vertically-movable plate, 0, a series of heating devices having their flame-tubes below the level of the plate 0 in its raised position, and solder and heating tubes arranged upon a higher plane than the flame-tubes of the heating-stations, substantially as described.

In combination, a can-seat, a verticallymovable plate, a, a series of heating devices having their flame-tubes below the level of the plate 6, a segmental shield on said plate, and flame and solder tubes in approximately the same horizontal. plane and in line with the edge of the can to be soldered, substantially as described.

4:. In combination, a can seat, a flamechamber, a vertically-nlovable plate, (3, forming the upper part of the llamc-chamber, and means for raising said plate, consisting of a cam, 7L, the sleeve f, and connections between the sleeve and cam, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
